Aaron Donald

For Donald to affect games the way he does as an undersized defensive tackle is remarkable, and he's definitely one of this generation's most uniquely great players. Listed at just 6-foot-1, 285 pound...

Donald became an instant star after entering the starting lineup Week 6, earning Defensive Rookie of the Years honors as one of the league's most explosive linemen. A consistent tackler, Donald's pass rush improved late in the year with six sacks in the last seven games. His nine sacks were the most by a rookie in three years and second among defensive tackles last season. He also had 18 tackles for loss (2nd among DT, 4th among DL). Those numbers could take a jump this year with more snaps — he should see at least 800 this season after playing only 705 snaps last year.

Although Michael Brockers and Kendall Langford are the incumbent starters, Donald is going to see plenty of game time after being drafted 13th. Donald was a menace to offenses in college and with so much defensive line talent in St. Louis, doesn't have the immense pressure of starting right off the bat.
